@ benzo yea will keep the stock muffler will try another shop i fig he was full of shit.. im gunna look around for a second opinion. It's like these guys get nervous wen u bring a BMW in for work. guess in their mind they are thinking liability

Pipe is pipe. Doesn't matter if it's on a Buick or a BMW. I've heard that a res delete running stock muffler u can't tell much. But be sure to do a before and after. If it sounds good I'll be doing the same

Removing the resonator was the first thing that I wanted to do but at the mufffler shop the mecanic said that it won't change the sound if you keep the OEM muffler. The OEM muffler is the main reason why the exhaust is so quiet. Replacing your muffler to any aftermarket or BMW PE is the only way to get more sound and combine that with the resonator delete will increase the sound even more.

Therefore I have scrapped the idea of the res delete until I get an exhaust. I have been looking for a 2nd hand BMW PE or Eisenman or even the RE Ikon exhaust but no luck yet.

Read a lot about the MMW CS Muffler and has great reviews but I don't want to buy it until I hear it in person.

From first hand experience on my E90 325i, I can confirm that a resonator delete does nothing with the stock muffler on. But when pairing it with an aftermarket muffler, it does change the sound a bit.

so my question would be, what is a main difference between going to BMW to get Performance Exhaust vs getting Y pipe and removing resonator on stock and putting a new muffler on it? because i think the latter will be much much cheaper.

My friend has a mcoupe and he changed his muffler and the tip for $700 (magnaflow) but if i take it to BMW they gonna charge me like $1200 i believe.
